Electrical connector



Nov 1, 1949. J. ORLANDO ELECTRICAL CONNECTOR Filed July 12, 1946 Patented Nov. 1, 1949 UNITED STATES PATENT OFFICE ELECTRICAL CONNECTOR J eano Orlando, Salt Lake City, Utah Application July 12, 1946, Serial No. 683,004

My invention relates to electrical contacts and has for its object to provide a new and highly efficient connector for connecting the wires of an electrical circuit into a wall plug or any other place where it is desired to connect a wire in a quick and simplified manner.

A further object is to provide a connector for electrical plugs which eliminates the need for screws and other like means of attaching the wire into the plug.

A still further object is to provide a simplifled, easily operated, economically manufactured connector into which the electrical wire is inserted and the wire locked in place by closing of the side walls of the connector by pinching them onto the wire with a pair of pliers or other suitable device.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings- 3 Claims. (Cl. 173-361) Figure 1 is a vertical section through an electri-cal plug showing my device in use therein.

Figure 2 is a plan view of the plug.

Figure 3 is an enlarged view of one of the contacts of a plug, removed therefrom, showing how my device would appear when used therewith.

Figure 4 is a diametrical section of my conhector.

Figure 5 is a section on line 5-5 of Figure 4.

In the drawings I have shown the plug body as A, into which wires are passed through the tubular end 5. The contacts 8 and I of the plug are identical and in Figure 3 I have shown the contact 6 with my connector B attached thereto.

My connector B consists of a hollow spherical conductor body 8 having the top end open at 9 and having a cylindrical base which is extended down and adapted to be passed through the plate ll oi the contact 8 through a hole It in one end thereof. The bottom end of the cylindrical base I0 is then swedged out or riveted at It to attach the contact through and to the plate Ii.

Within the spherical body 8 of my connector I provide a cylindrical soft metal tube H, which tube is adapted to be drawn inwardly by compression of the side walls of the spherical body 8 with the bore of the tube It adapted to engage the bare portion oi the electrical wire and to grip the wire by the compression oi the metal therearound. Ii desired, the end or the wire may be pressed up through the open end 9 and bent over to insure that it would be impossible to withdraw the wire from the connection. A screw S, shown in Figures 1, 2, and 3, is used to attach the plate ll into the plug body A, but any suitable means may be utilized to attach the plate II, and as this is an old expedient, no claim is made thereto.

Having thus described my invention, I claim:

1. An electrical contact comprising a hollow spherical body having the top end open; means to attach the body to a contact plate or base; a cylindrical soft metal tube carried in said spherical body through which the wires may be passed and to which they may be secured when the spherical body is compressed therearound by a suitable distorting pressur applied to the periphery of said spherical body.

2. An electrical contact comprising a hollow spherical body having a tubular base extending therefrom and an opening through the top of the body and through the base; means to attach the base to a contact plate; a cylindrical metal tube carried in said spherical body adapted to engage a wire when inserted through the cylindrical base or top opening when the spherical body is compressed therearound by pressure means.

3. An electrical contact adapted to be distorted by external pressure applied thereon to engage a single strand wire comprising a spherical body having a hole diametrically therethrough; an extended cylindrical base aligned axially with said hole said base being adapted to be riveted or expanded through a base plate or contact member; a cylindrical soft metal tube carried in said spherical body situated so that the single strand wire passed into the spherical body will pass through the bore of the tube and compression from any side or area of the body will bind the wire, tube and sphere into electrical connection.

JEANO ORLANDO.
